We will now use the head from the iron to melt the hot-melt tape in between the broken seam layers, to bond them together again.

Carefully check the tape is underneath the old taped seam and not protruding out from the edges. Position the heated iron on top of this area, and apply light pressure, for up to 10 seconds.

Let the area cool down, and then check whether the hot-melt tape has melted and bonded the defect successfully. If it has not, apply the iron again, and increase the pressure a little. Continue this process until it is fully glued down.

Tip: you may find in this process, that some extra hot-melt tape is needed in some areas. simply cut some more small pieces and slide them between the seam, and repeat the steps above.
